This time the focus was CT of the thorax. 120 radiologists, radiographers and physicists representing all hospitals in the South-Eastern Norway Regional Health Authority attended the Forum. Among topis discussed were; surgical consequences of the investigation, treatment of emphysema with bronchial valves, image quality and radiation dosis in CT thorax, contrast optimalization, protocols and pitfalls in lung emboli, protocols and pitfalls in tumor protocols, spectral imaging and finally ultra low dose CT thorax. The meeting was rounded up with plenary discussions.

The Intervention Centre, in cooperation with Hermes Partnership and COST Action IC0905-TERRA, organized the “Workshop on Sensor Communications & Technologies, Body Area Networks, e-Health Services and Standardization.” This event took place on April 4, 2014, in Florence, Italy, in the framework of the 8th International Symposium on Medical Information and Communication Technology (ISMICT) sponsored by the Institute of Electrical and Electronics Engineers (IEEE). The workshop consisted of high quality technical presentations and a general discussion in which the participants identified future trends and new research directions for the advancement of medical sensing technology. Dr. Raúl Chávez-Santiago from the Intervention Centre delivered the keynote talk “Dual-Band Cognitive Radio for Wearable Sensors in Hospitals,” in which he emphasized the need for novel and more effective techniques to mitigate interference in sensor networks for healthcare.
Aasmund Fretland was awarded the 500 USD prestigeous "Best Oral Poster Presentation Price" at the 11th World Congress of the International Hepato-Pancreato-Billary Association in Seoul, Korea, March 22-27 2014. The presentation concerned IL-6 in patients included in the ongoing randomised clinical trial Oslo-CoMet Study. The principal investigator of the Oslo-CoMet Study is professor Bjorn Edwin from The Intervention Centre. The picture shows Aasmund Fretland presenting the poster at the conference that gathered around 2500 international delegates.
Research Council of Norway hosted an Idea Lab with the topic : "Towards a zero emission society". During 5 hectic days 27 selected researchers from different disciplines generated four project proposals. The project group behind "Holistic monitoring of indoor environment" included professor Ilangko Balasingham from The Intervention Centre. The research challenge in this projectis how energy consumption can be radically reduced by use of rapidly responding technologies and materials. (Photo:Forskningsrådet)
On January 13-14, 2014, the Nordic Chapter of the International Society for Magnetic Resonance in Medicine (http://www.ismrm.org/nordic/) with Kyrre E. Emblem (chair) and Atle Bjørnerud from the Intervention Centre organized a two-day ‘hands-on’ course in neuro MRI: Perfusion, Diffusion / DTI and BOLD-fMRI analysis at Rikshospitalet, Oslo University Hospital.
Invited speakers where experts from the Nordic countries and they shared their knowledge on advanced neuro MRI with over 80 participants in total.
On October 24 2013 Andreas Espinoza defended his thesis on Myocardial monitoring by epicardial ultrasonic transducers. Andreas Espinoza and co-workers have developed an ultrasonic system for attachment on the heart for continuous assessment of myocardial function during cardiac surgery. As the patients undergoing cardiac surgery are getting older, and the surgical treatment is increasingly complex, this risk for complications increase. Perioperative ischemia is an important predictor for adverse patient outcome. Echocardiographic assessment for early detection of myocardial ischemia is superior to ECG or hemodynamic monitoring, but is performed intermittently.

Rahul Prasanna Kumar, Fritz Albregtsen, Martin Reimers, Ole Jakob Elle and Bjørn Edwin, from The Intervention Centre and Institute of Informatics, won the 3rd prize for the “Inven2 Best Innovative Idea 2013” along with a cash prize of 10.000NOK. The winners were selected from competition among 84 ideas and inventions. The project is titled “Fast and user-friendly blood vessel segmentation method” and is part of Marie Curie EU project, IIIOS. The work is on a novel blood vessel segmentation method, which is shown to be much faster than commonly used techniques.See Inven2 for more info in Norwegian on the award.
On September 3 2013 Fatemeh Sadat Kazemeyni defended her thesis at Faculty of Mathematics and Natural Science Department of Informatics and The Intervention Centre OUS, Faculty of Medicine. Supervisors were professors Ilangko Balasingham, Olaf Owe, Einar Broch Johnsen. Associate professor Elena A.Troubitsyna, Åbo Akademi University, Finland, senior researcher Sasitharan Balassubramaniam, Tampere University of Technology, Finland, and associate professor Ellen Munthe-Kaas, Department of informatics, University of Oslo were in the adjudication Committee.
Abstract: Wireless Sensor Networks (WSNs) consist of a number of nodes responsible for monitoring data and transmitting it to base stations. Power efficiency is an important issue in WSNs, because nodes are powered by batteries. An effective approach to improve the efficiency of WSNs is collaboration among nodes. In this thesis, we study the problem of applying rewriting logic for formal modeling and analysis of cooperative communication in terms of power consumption. Formal methods provide an abstract model of WSNs and can simulate and validate them, in spite of simulators which can not validate WSNs.
In their report receiving online publication in Nature Medicine, investigators Kyrre E. Emblem and Atle Bjørnerud from the Intervention Centre present a new paradigm in cancer diagnostics by Magnetic Resonance Imaging (MRI) coined as Vessel Architectural Imaging, exploiting an intriguing and overlooked hysteresis effect in perfusion MRI that reveals new knowledge of tumor vessel type and function. Preliminary data show improved microcirculation and oxygen concentrations combined with reduced vessel calibers in brain tumor patients (glioblastoma) receiving anti-angiogenic treatment and the extent of this response correlate with survival.

On June 17th 2013 Airazat M. Kazaryan defended his thesis "New minimally invasive techniques in the treatment of patients with lesions in the liver: laparoscopy and extracorporeal high intensity focused ultrasound".
Laparoscopic liver resection has shown classical advantages of minimally invasive surgery over the open counterpart. In spite of introduction in early 1990-s only few centres worldwide adapted laparoscopic liver resection to routine practice. It was due to considerable technical challenges and uncertainty about oncologic outcomes. Various ablative techniques have been developed last 2 decades in parallel with laparoscopy. High intensity focused ultrasound (HIFU) attracts special interests due to its fully non-invasive nature.
The main goal of this thesis was to estimate and develop new minimally invasive techniques in the treatment of patients with lesions in the liver: laparoscopic surgery and HIFU. Image from left: professor Bjørn Edwin, Per Kristian Hol MD, PhD, Airazat M. Kazaryan PhD and professor Erik Fosse.
